mode
(Position-
ing)
Pulse output
starts at the
specified fre-
quency and
stops when the
specified num-
ber of pulses
have been out-
put.
(The number of
pulses cannot
be changed dur-
ing pulse out-
put.)

The frequency
accelerates or
decelerates at a
fixed rate and
stops immedi-

Pulse output
starts at the
specified fre-

stops immedi-
ately when the
specified posi-
tion is reached.
(The target posi-

changed during
positioning
(pulse output).)

positioning
Use for abso-

ing
(electronic
cam control)
with a sin-
gle-phase
output, no
acceleration
or decelera-
tion, and tar-
get position
changes in a
fixed time
interval. (See
page 191.)
The frequency
accelerates at a
fixed rate, decel-
erates at a fixed
rate, and stops
when the speci-
fied number of
pulses have
been output.
(The number of
pulses cannot
be changed dur-
ing positioning
(pulse output).)
